Disable Sticky Post Option

How do I remove the “Stick this post to the front page” check box? I want to remove it so nobody can use it. I don’t want to install any other plugin that manages permissions. I just want to remove it from the script. What should I edit?

Are there any lines I need to add on functions.php to totally disable sticky posts? I tried this:

update_option(’sticky_posts’, array());

But it didn’t work. Thanks
